The Grooming of Unintended Consequences

Pubic lice, the crab-shaped insects that have dwelled in human groins since the beginning of history, are disappearing. Doctors say bikini waxing may be the reason.

Waning infestations of the bloodsuckers have been linked by doctors to pubic depilation, especially a technique popularized in the 1990s by a Manhattan salon run by seven Brazilian sisters. More than 80 percent of college students in the U.S. remove all or some of their pubic hair -- part of a trend that’s increasing in western countries. In Australia, Sydney’s main sexual health clinic hasn’t seen a woman with pubic lice since 2008 and male cases have fallen 80 percent from about 100 a decade ago.
